The subdev core code currently rely on the subdev open handler to initialize the file handle's pad configuration, even though subdevs now have a pad operation dedicated for that purpose.
As a first step towards migration to init_cfg, call the operation operation in the subdev core open implementation. Subdevs that are haven't been moved to init_cfg yet will just continue implementing pad config initialization in their open handler.
